Answer 2

Given,

Measurement starting from = 1 cm

measurement ends at = 12 cm

To find,

The correct length of the straight line.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now, any centimetre scale starts from 0 marking and upto 1 centimetre mark, it covers a distance of 1 centimetre.

So, in this case there will be one centimetre extra added value in the final measurement.

Actual measurement = 12 cm - 1 cm = 11 cm

Hence, the actual length of straight line is 11 cm.
